Komparativna analiza rezultata dosadašnjih istraživanja zlatonosnih nanosa Volujskog Ključa i Ujevca u dolini Peka

Abstract

Jedna od osnovnih metalogenetskih karakteristika Istočne Srbije su brojne pojave i ležišta nanosnog zlata. Na osnovu analize rezultata starijih (1907. i 1947-1952. god) i novijih istraživanja zlatonosnih nanosa Peka (Volujski Ključ i Ujevac od 1989. godine), došlo se do saznanja da su sadržaji zlata u nanosu preko dva puta veći od sadržaja utvrđenih ranijim istraživanjima. To naravno treba potvrditi i ako bi se pokazalo tačnim, u tom slučaju bi lokalnost Volujski Ključ, sa prosečnim sadržajem zlata od oko 0,25gr/m3, bila ekonomski interesantna, odnosno mogla bi se rentabilno eksploatisati.

Analyzing the researches of gold bearing alluviums of the river Pek until now, especially the Volujski Kljuc locality, we came to the conclusion that the middle content of gold is about 0,25g/m3. This particularity changes the picture of potentiality of the Volujski Kljuc alluviums and shows that the mentioned deposits could be payable explored. In the Ujevac locality, on the basis on new researches (1989 year), the content of gold in this deposit is unexpectedly low. Because of that, further exploration on this part of alluvium is needed. Some special problems appeared during these researches that can be eliminated by using good equipment, by the regular induction of the researching technology and by sampling the deposit regularly. The results of gold content obtained from the newest researches (since 1997), by using KNELSON concentrator, are even bigger from those obtained in 1988 and 1989, especially in fine fractions (+0.02-0.00mm) The latest researches of alluviums of the river Pek gave the unquestionably positive results, which approved the money invested in it, and relegates on further researches of these deposits.
